1 Claim; (01. 254-88) This invention appertains to novel and useful improvements in lifting devices particularly adapted for use in raising selected portions of vehicles.

An object of this invention is to provide an improved lifting device or jack having means for actuating the same accessibly and easily from the described characterized by ease of operation,"

facility in actuation, obviating the necessity of placing and actuating a lifting device from the front or rear portion of a vehicle.

Ancillary objects and features of novelty shall become apparent to those skilled in the art, in following the description of the preferred embodiment of the present invention, illustrated in the accompanying drawings, wherein:

Figure 1 is an elevational side view of the preferred embodiment of the present invention, parts being shown in section to illustrate details of construction and showing the preferred form of operating the invention when used in conjunction with an automotive vehicle;

Figure 2 is an elevational side view of the preferred form of the present invention;

Figure 3 is a sectional view of the invention disclosed in Figure 1 and taken substantially on the line 33 thereof and in the direction of the arrows;

Figure 4 is a transverse sectional view, taken substantially on the line 4-4 of Figure 1 and in the direction of the arrows;

Figure 5 is a sectional view of the invention disclosed in Figure 4 and taken substantially on the line 55 thereof and in the direction of the arrows;

Figure 6 is a fragmentary elevational view, showing particularly one form of the detachable extension means forming part of the present invention;

Figure 7 is a longitudinal sectional view of the invention disclosed in Figure 5 and taken substantially on the line 1'I thereof and in the direction of the arrows, and

Figure 8 is a transverse sectional view showing a detail of construction in Figure 1 and taken 2 substantially on the line 8-8 thereof and in the direction of the arrows.

Referring now in detail to the illustrated pre-:

ferred embodiment of the present invention, like reference characters are used throughout to indicate elements of similarity.

This invention has been developed to provide an improved device for facilitating repair operations of vehicles, particularly such operations which entail the removal of a wheel, brake drum or other associated adjacent mechanism. I In the newer model automotive vehicle, an appreciable amount of body portion protrudes overthe front and rear axles thereof. Also, it is the tendencyof automotive vehicle manufacturers to extend the vehicle as close as practicable to the road It is known that this type of construction gives rise to difliculties in using certain conventional types of jacks and also, the utility of jacks for lifting the vehicle from contact with bumpers and the like have proved to be unsafe and'generally unsatisfactory in operation. It is within the purview of the present invention to provide a device for lifting selected portions of automotive vehicles without resorting to contacting bumpers extension l2 secured thereto. To assist in manu- I facture, the said base member and extension may be constructed of two or. more elements if so desired. This however, is a mere matter of choice in construction to aid in commercial prac ticability. I

A lifting means is provided in the said base l0,

while a portion thereof extends through the extension l2. means may be utilized in conjunction with the zpresent invention, either mechanical, hydraulic or compressed air actuated. For illustration pur-' poses, a mechanical lifting means ii's's provided. A sleeve i4 is rotatably received in a suitable bore [6, provided in the said base It). A slot I8' -extends longitudinally of said bore IB and a pin- 20, secured to said sleeve I4, is reciprocatively journaled in the said slot I8. This construction prohibits rotational movement of the said 1 Any form of conventional lifting relation to the interior of the extension. 'A'worm 34 is received on thesai'd shaft 28 and engages the gear 24. It is quite apparent from an inspection of Figure 4 that rotation of the said shaft 28 produces movement of the sleeve I 4 parallel to the longitudinal axis thereof.

A conventional receptor 36 is secured-to the said shaft 28 exteriorly of the extension l2. This receptor is provided for the purpose of receiving a conventional handle mechanism 38 removably therein.

.It is noted iatthis .point that the aforementioned sections of the base andextensionmay bejoined by any suitable conventional .means including welding, brazing, riveting .or as disclosed by suitable conventional .bolts 40 and associated nuts 42. As.-many .of these. bolts may be employed as dictated by. soundengineering principles.

The said extension 12 is preferably provided with-a ramp 46-atone 'endthereof to facilitate theentry ofa Vehicle wheel thereon. As isquite apparent .from an inspection, of .Figure v1, the inventionis simplyplaced.infront of. a wheel to be removed and the vehicle .is .moved forward thereon. Obviously, all of the actuating mechanism-to be treated manuallywithin a convenient location extending perpendicularly from the side of an automotive vehicle. .:A,-.recess -48 :may be provided at the upper portion of saidextension l2, thereby forming. guide means iniholding the tire 50 of a conventional wheel therein.

Various types of vehicles are;;provided with different-types of spring-suspension,.steering gear and the. like. In order that the present invention may-me utilized withsubstantially .all'types :of commonly known vehicles, arms :are selectively anddetachably secured to the upper, portion .of thesaid sleeve l4. Any suitable se'curingmeans is utilized in attaching'variously .conflguredarms tothe upper 1portionof said sleeve. ..A..slotted extension 52 may besecured. tofthe said sleeve I4 and intersecting .uapertures :may be ,provided in .the .arm :54, said.last mentioned apertures being complemental to .the s slotted --=extension :52. The arm or extension means 54 may berested upon the sleeve l4. anda-con-ventional .pin:.extended through onefof the saidintersecting. slots. Thenarm 54, .disclosed in Figurev 2, willlengage suitable: under carriage. elements of most conventional vehicles howeven variation as to. shape. and size of the saidlarm 54'zmay'be employedin.

in the lower of said bends. This construction permits the engagement of the slot 62 with a brake drum or similar braking element. This type of construction is employed when it is impractical to use one of the arms of the class described and disclosed at 54. Of course, if found desirable, the dovetail construction disclosed in Figure 6, might be employed in the construction of Figures 1 to 5 in lieu of the securing means disclosed therein.

In operation, all thatis necessary to "position the jack in the desired operative position is to *place the same in the front of the wheel to be I removed and drive or otherwise move the vehicle of the'un'de'r'carr'iage of a vehicle.

on the extension and in the recess 48. Then,

aactuation of the handle means 38 moves the selected arm 54 or 60 against a suitable element The said :unde'rncarriage is then lifted until the wheel and tire is out of contact with the extension l2. The wheel ,or wheel component may then .be easily removed for repair or otherpurposes. ItsiS-WEH to .note at this point that the operator of the invention need never crawl under his vehicle for the removal of a wheel having a deflated tire thereon.

It is apparent that adevice capable of .performing all of the specifically mentioned objectshas beendescribed herein. However, it is apparent to those skilled in the vart, .that various changes including omissions, additions and rearrangement of elements maybe madetherein without departing from the spirit of the invention. .z-Accordingly, limitation is-sought only in accordance with the scope of the following claim.

. Having thus described .;the ;present invention what is claimed as novel: and .improvedris aas follows:
